1 Claim. (Cl. 223-102).

This invention relates to new and useful improvements in sewing needles.

More particularly, the present invention proposes the construction of animproved sewing needle which can quickly and easily be threaded by touchor by sight and which will securely hold the thread once threaded whilesewing.

As a further object, the present invention proposes forming the needlewith an end threading slot so that the needle can be threaded from theend of the needle rather than through the eye or eye opening.

Another object of the present invention proposes constructing the needlewith a V-shaped end notch at the eye end of the needle for finding theend threading slot by touch or by sight.

Still another object of the present invention proposes forming theneedle with side threading slot openings connecting with both the eyeopening of the needle and with the end threading slot opening forthreading the needle by touch or by sight.

Another object of the invention proposes constructing the needle withtwo spaced members at the eye end of the needle adapted and arranged toform the eye opening, the end threading slot opening, the end notch andthe side threading guide slot openings of the needle.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings,

and to the appended claim in which the various novel features of theinvention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a fragmentary front elevational view of the eye end of aneedle constructed and arranged in accordance with the presentinvention.

Fig.- 2 is a side elevational view of the structure shown in Fig. 1.

Fig. 3 is an end view of the structure shown in Figs. 1 and 2.

Fig. 4 is a view similar to Fig. 1 but illustrating a modification ofthe present invention.

Fig. 5 is an end view of the structure shown in Fig. 4.

Fig. 6 is a sectional view taken on line 6--6 of Fig. 4.

Fig. 7 is a view similar to Fig. 2 of the structure shown in Fig. 4. I

Fig. 8 is a rear view of the structure shown in Figs. 4 and 7.

Fig. 9 is a sectional view taken on line 99 of Fig. 8.

The needle, in accordance with the first form of the invention shown inFigs. 1 to 3, inclusive, has a shaft or shank 15. v

The end portion 16 of the shank shown has an eye end 17 and the shankmay be made either for use as a hand needle or as a needle for a sewingmachine. The shaft may be of any cross section desired, round orelliptical.

Eye end 17 of shaft 15 has a V-shaped end guide notch 18 with the apex19 disposed at the axis of the shaft. In the shaft adjacent to andspaced from the eye end 17 is shaft. j )Also in the eye end 17 of shaft15 isv an end threading slot opening -21. extendingfr'o'm the eye.endi17.si1bstan-. tially. the,.-l'ength' of tthe' nee'dle eye opening,20.Tand,fd1s} I Paitentedv ctzanats the usual'needle ey'eopeningzllwhichzpreferablyis ellipti' cal in shape posed at 'rig'htangles to theeye opening. That is;

eye opening 20 extends from the top 22 of the needle to the bottom 22'of the needle and the end threading slot opening 21 extends from one.side 23 to the other side 24 of the needle. the needle are, of-course,referred to only for convenience I in the description as the needle canbe used in any position desired. Adjacent the end 25 of the needle eyeopening 20 most remote from the eye end 17 of shaft 15 two sidethreading guides or slot openings 26 and 27 are provided. Thesidethreading slot openings 26 and 27' connect with both the eye opening 20and the end threading slot opening 21, as best shown in Figs. 1 and 2 IThe'needle can be threaded either from the eye end 17 through the endthreading slot opening 21, in the regular manner through the needle eyeopening 20, or through either of the side threading slot openings 26 or27.

Themodification of the invention illustrated in Figs.

v4 to 9, inclusive, is characterized by the provision of a needle shaft30having a cylindrical shank 31 and an eye end 32.

Eye end 32 is formed with two hook-shaped members 33 and 34 having fixedarms integrally joined with the shank 31. The arms are laterally spacedone from another to form an end threading slot opening 35. The members33 and 34 are V-shaped in form with apexes 36 and 37 spaced and offsetone from another to form an end .Thefree arms 39 and 40 of members 33and 34 termi- I v nate substantially midway between the ends of the eyeopening 43 to retain a sewing thread effectively in the eye opening. Theshank 31 of the shaft is cylindrical in form to facilitate its passagethrough a fabric being sewn. The

diameter of the shank exceeds the combined maximum lateral thickness ofmembers 33 and 34 as clearly shown in Figs. 5 7. Thus, the free arms 39and 40 cannot catch in the threads of the fabric being sewn when theneedle is pushed or pulled through the fabric from, the shank end. Inaddition, the arms of the V-shaped members taper substantially to apoint at end 32 with apexes 36 and 37 so close together that the needlecan enter eye end first into a fabric with the shank following after andwithout the thread of the fabric catching in the guide notch 38.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and that various changes andmodifications-may be made within the scope of the invention as definedin the appended claim.
